Los juegos de simulación en la EGB: una investigación en el área de las Ciencias Sociales

Resumen

Las autoras tratan de probar la eficacia de los «juegos de simulación» en la enseñanza de la Geografía en la EGB. Para ello realizan la adaptación de un juego aplicándolo a los niveles escolares de 5.° y 7.°, y comparan los resultados de los grupos experimentales con otros de control. Las conclusiones a que llegan se basan en cuatro tipos de pruebas: de memoria, de razonamiento, de aplicación y de valoración del juego. Los resultados obtenidos muestran que estas actividades dan mejores resultados en 7.° que en 5.° y favorecen principalmente a los sujetos menos dotados que ven aumentados sensiblemente sus rendimientos.     

“Maestro,what is ‘quality’?”: Language,literacy, and discourse in project‐based science

Recent curriculum design projects have attempted to engage students in authentic science learning experiences in which students engage in inquiry‐based research projects about questions of interest to them. Such a pedagogical and curricular approach seems an ideal space in which to construct what Lee and Fradd referred to as instructional congruence. It is, however, also a space in which the everyday language and literacy practices of young people intersect with the learning of scientific and classroom practices, thus suggesting that project‐based pedagogy has the potential for conflict or confusion. In this article, we explore the discursive demands of project‐based pedagogy for seventh‐grade students from non‐mainstream backgrounds as they enact established project curricula. We document competing Discourses in one project‐based classroom and illustrate how those Discourses conflict with one another through the various texts and forms of representation used in the classroom and curriculum. Possibilities are offered for reconstructing this classroom practice to build congruent third spaces in which the different Discourses and knowledges of the discipline, classroom, and students' lives are brought together to enhance science learning and scientific literacy. © 2001 John Wiley & Sons, Inc.

Neurocognitive and Temperamental Systems of Self‐Regulation and Early Adolescents’ Social and Academic Outcomes

ABSTRACT— The aim of the current study was to examine the role of individual differences in neurocognitive and temperamental systems of self‐regulation in early adolescents’ social and academic competence. Measures used in the study included the Attention Network Test, the Early Adolescence Temperament Questionnaire, a peer‐reported Social Status Questionnaire, a self‐reported measure of Schooling Skills, and information on grades obtained by the students in a variety of school subjects (n= 69 12‐year olds). Results showed that efficiency of the neurocognitive network of executive attention is related to academic outcomes, particularly in mathematics, as well as to aspects of social adjustment. Temperamental effortful control appears to be a significant predictor of all dimensions of school competence assessed in this study and mediates the relationship between social adjustment and poor schooling outcomes. These data suggest that individual differences in systems of self‐regulation are central to understanding processes of learning and social adjustment in the school.     

The Effects of Physical Abuse on Children's Social Relationships

Social behavior and peer status of 87 physically abused 8–12-year-old urban children were compared with those of 87 case-matched nonmaltreated classmates. Peer nominations and peer ratings were collected in classrooms, social networks were assessed by child interview, family variables were assessed by interviewing mothers, and behavior problems were rated by parents and teachers. Significant findings were that abused children had lower peer status and less positive reciprocity with peers chosen as friends; they were rated by peers as more aggressive and less cooperative and by parents and teachers as more disturbed; and their social networks showed more insularity, atypicality, and negativity. Social behavior as perceived by peers accounted for a significant portion of the variance in social status; global disturbance measures did not add to this association. Results are discussed in terms of a context of family violence in the development of social maladjustment.     

What if we could Imagine an Ideal University? Narratives by Students with Disabilities

This article presents the results of a project entitled, ‘Analysis of University Barriers and Aids Identified by Students with Disabilities’, carried out in a Spanish University. The study used the biographical–narrative methodology, which emphasises the importance of people talking about themselves without silencing their subjectivity. Different types of data collection instruments, such as biographic interview, timelines and photography, were employed to acquire this information. The Results section presents proposals made by students with disabilities which could contribute to developing a more inclusive university. Some of their suggestions were that students with disabilities should be better informed and oriented, academic staff should be better trained to favour their educational inclusion, the settings and infrastructures should be accessible, and universities should be prepared to deal with people with disabilities. The conclusions discuss the main findings of the analysis, comparing them with other previous studies, and making some proposals that help universities progress towards inclusive education.     

Maternal teaching of the symbolic function of a scale model / La enseñanza materna de la función simbólica de una maqueta

This study explores how mothers naturally guide their children in the use of a symbolic object, a scale model. Nineteen mothers, along with their two-and-a-half-year-old children, participated. The children had to find a toy hidden in a small room by using a scale model that represented it. It was found that mothers used three kinds of strategies: model-room correspondence, life experience and the names of the objects; with correspondence being the preferred strategy. The mothers were very responsive to their children, offering feedback in order to evaluate both their correct and incorrect searches. The corrective feedback affected the children’s performance when mothers had previously used strategies like correspondence and experience, but not in the case of name. In general terms, the results illustrate how mothers naturally guide the cultural knowledge of their children, structuring the interaction in a particular way and providing teaching and correction strategies in line with the responses of their children and the characteristics of the task.     

Teachers negotiating discourses of gender (in) equality: the case of equal opportunities reform in Andalusia

This article is focused on the analysis of the narratives produced by a group of teachers, experts in coeducation, while they were discussing their everyday activities. They are responsible for the implementation of a Plan for Gender Equality in public secondary schools in Andalusia (Spain). This study is based on contributions about doing gender view, according to which gender is not an attribute of individuals, but a way of making sense of interactions and practising a complex system as functioning on three levels: sociocultural, interactional, and individual. We use these levels to understand gender culture in schools through teachers’ discourse. Our interest lies particularly in the meanings, contradictions, difficulties, and conflicts experienced by expert teachers in co-education. Our study was based on group discussions with teachers in charge of the plan for equal opportunities between women and men in school settings. Results show teachers’ conflicts about meanings and how they are supposed to apply the Equality Plan. We observed interactional levels during these conflicts and analysed how teachers construct and validate their discourse.     

Effect of bike-fit in the perception of comfort,fatigue and pain

ABSTRACT

The aim of this study was to assess the influence of different bike positions on the perception of fatigue, pain and comfort. Twenty cyclists underwent three tests that involved cycling for 45 min at their individual 50% peak aerobic power output while adopting different positions on the bike. Participants performed the cycling tests adopting three positions defined by two parameters (knee flexion angle [20°, 30°, 40°] and trunk flexion angle [35°, 45°, 55°]) in random order. Angles were measured using a 2D motion analysis system during cycling and applying Fonda’s correction factor. Perceptions of comfort, fatigue and pain were reported before the end of each test. The combination of 40° knee flexion and 35° trunk flexion was perceived as the most uncomfortable position. Moreover, greater knee flexion had a negative effect on trunk comfort, accompanied by greater levels of fatigue and pain perception in the anterior part of the thigh and knee. In conclusion, cyclists perceived the most comfortable position to be when the saddle height was within the recommended knee angle (30° calculated from the offset position or 40 ± 4.0° of absolute value). Upright trunk was found to be the most comfortable position for recreational cyclists, where aerodynamics is not so important. Cyclists’ bike perceptions should be taken into account when it comes to choosing the most beneficial position, since this can play a role in injury prevention and enhance cycling performance.
